This motor is a single cam, all motor D16! And the customer won 1st place at the Battle of the Imports in his bracket!! Congratulations Will!
Anyway, Will, you owe me a set of Bosch plugs! Will didn't think in a million years that the Bosch would make power...then I put them in and changed his mind. We love changing peoples minds!
